I just recently got some Oil paints... But I have very little clue as to how to use them... Their water mixable ones... and I was wondering if anyone knew about a good tutorial for em? (I've already searched Google and PK)

IDA-71 is a complete system, designed not only for shallow water oxygen use, but also for mid-depth Nitrox use (using a belt-worn Nitrox system), as well as for high altitude parachuting operations and for use as a supplemental oxygen system for high-altitude helicopter crew use! Thus the system is really the "Universal" IDA-71 system.

WARNING:It is VERY important to understand that once the Nitrox system becomes active that there is NO access to the internal 02 supply, as it is TOTALLY isolated once the Nitrox system becomes active at about 40 feet. Once passing the depth where the system switches over to Nitrox, the ONLY additional oxygen available comes from the chemical reaction taking place when using the special (and unavailable) Russian scrubber chemical. PAY ATTENTION! I'll say it again: The system relies ONLY on the 02 produced by the Russian chemical carried in one of the two scrubbers. Failure to understand this WILL result in your death if you dive one of these without knowing this.

A word about this Russian 02 producing chemical: This is a nasty exothermic stuff that is very caustic when exposed to water. Trust me, it's REALLY bad stuff. Actually, not only will it KILL you if you breathe in a bit of it after it gets wet, the cannister that it's contained it will get hot enough to MELT its way right through a steel ships-deck if it becomes water-saturated, and lastly it contains Asbestos, so you are playing with lung damage even on a good day. I TOLD YOU that it was bad stuff, so now do you believe me? Trust me on this: Don't even think of trying to use any of this stuff.

Is an extremely well designed and executed system for performing saturation or deep surface-supplied tethered diving. There is nothing else in the world that does even close to what this rig was designed to do, and Western users of saturation diving techniques could learn a lot from this piece of equipment.
